City Nature Challenge 2025

Join the City of Boroondara in the 2025 City Nature Challenge. It’s a global event where people compete to find and document as many wildlife and plants in their city as possible. 

You can help put Boroondara's flora and fauna on the world map and gather important data for scientists. This year's challenge runs from Friday 25 to Monday 28 April.
